NCM-5.15 questions and answers

An administrator is implementing a VDI solution. The workload will be a series of persistent desktops in a dedicated storage container within a four-node cluster. Storage optimizations should be set on the dedicated storage container to give optimal performance including during a node failure event.

Which storage optimizations should the administrator set to meet the requirements?

An administrator needs to make sure an RF2 cluster can survive a complete rack failure without negatively effecting workload performance. The current cluster configuration consists of the following: 30 nodes: distributed 10 nodes per rack across three 42U rack Each nodes is configured with 40TB usable storage all flash (Cluster Total 1.2 PB Usable)
Current cluster utilization is 900TB storage

Which configuration changes should be made to make sure that the cluster meets the requirements?

While creating an image placement policy on the organizations AOS 5.15-based Nutanix cluster, the administrator wants to ensure there are no restrictions on using the selected images on clusters outside of the identified set.

What type of Policy Enforcement must the administrator choose?

An administrator needs to evaluate if the existing configuration of Protection Domains meets the specified corporate recovery policy for SQL Data. The corporate policy requires that all SQL Servers be recoverable at the DR site within 30 minutes, and must result in a maximum of 60 minutes of data loss. SQL data must be required.

The protection domain is configured as follows: Application consistent snapshots are enabled
The SQL server VMs are assigned to the Protection Domain as their own Consistency Group
The Protection Domain schedule is configured as snapshots taken every 90 minutes from 7 am until 8 pm

What must be changed to meet the required policy?

An administrator receives reports about a Nutanix environment. The investigation finds the following;
VMs are experiencing very high latency Each node is equipped with a single SSD, utilized at 95%
Each node is equipped with three HDDs, utilized at 40%

Why are the guest VMs experiencing high latency?

An administrator is deploying an application that requires maximum I/O throughput for scratch data. The administrator is concerned that the throughput requirement is greater than what can be provided by a single cluster node.

What should the administrator do to meet this requirement?

An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the following considerations: Individual VMs will likely generate network throughputs in the range of 90-100Mbps
Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time Individual VMs will communicate with only a few (one or two) remote hosts at a time Multicast will not be used in the environment
The hosts are connected via two 1GbE network connections

How should the administrator configure the network bonds to meet this requirement while maintaining the simplest switch configuration?

An administrator is using Nutanix Move to migrate a Windows VM from ESXi to AHV. Automated guest preparation is failing with an error:

Account has UAC enabled error

The administrator is using the local built-in administrator account for the Windows VM Admin approval mode must remain enabled.

What should the administrator do to continue with the migration with Nutanix Move?

A customer has NearSync configured. When the administrator tries to restore a snapshot from 3 minutes ago, it is not available. The snapshots are happening at 15-minute intervals instead of at the 5-minute configured interval. When the protection domain was initially set up, the snapshots were happening at the expected 5-minute interval.

What should the customer do to enable the snapshots to happen at the expected interval?

Microsegmentation was recently enabled in a Nutanix environment. The administrator wants to leverage Prism Central to create a policy that will block all traffic, regardless of direction, between two groups of Vms identified by their category.

Which policy should be used to meet this requirement?

An administrator migrates a VM onto a new Nutanix cluster. After the migration, the administrator observes the following conditions: Cluster memory utilization: 64%
Cluster CPU utilization: 19%
Cluster storage utilization: 32%
Average VM CPU utilization: 25%
Average VM CPU ready%: 24%
Average VM memory utilization: 60%

Which two changes should the administrator make to improve VM performance? (Choose two.)

A new Nutanix cluster is ready for production on a remote site with no IT staff. Changes to the infrastructure will cost money and probably cause a cluster stop.

The administrator needs to perform a health check on the environment that should include: Network connectivity checks Network performance status Storage performance status

Which tool should be used to perform this test?

A guest VM is reported to have poor storage performance. It has an I/O profile of 80% read. 20% write, and the HDDs form more than 50% of the read source.

What should an administrator do to resolve this issue?
